If we're going to put it back in 9.2, then we shouldn't remove it now.We should just make it work. It's a three line
patch. If 9.2 is
going to meaningfully distinguish between write location and flush
location, then we may as well do the same thing in 9.1. Then we'll be
ahead of the game: not only will the view have the same columns in
both releases, but they'll actually have the same semantics in both
releases.
